LSEMAPHORE-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 346,243, dated July 27,1886.

Serial No. 164,663.

(No model.)

To all whom it may concern.:

Be itknown that I, WILLIAM THoRNnURGi-I, of Elyria, in the county ofLorain and State of Ohio, have invented certain new and usefulImprovements in Semaphore-Signals, of which the following is a full,clear, and exact description.

This invention relates to certain new and useful improvements in thesemaphore-signal, for which Unit-ed States Letters Patent No. 308,013were issued to me on the 11th day of November, 1881-.

The object of my invention is to simplify the mechanism for working thesignal-Wings in Asuch a manner that they occupy less space.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of my improved semaphore-signal, which isto be used on railroads for signaling trains, die., parts ofthe signalbeing broken out and others being in section, and part of the workingmechanism detached from the main signaling device, said detached partbeing the part which is located some distance from the signal, and isused for operating the signal. Fig. 2 is an enlarged detail side view ofthe mechanism for operating the rodsfor swinging the signalwings. Fig. 3is an edge view ofthe same. Fig. 4 is a plan view of the upright part ofthe apparatus. Fig. 5 is a detail side view of the jointplate on thepivoted end of a wing.

On the end ot' the semaphore-wing, A, a triangular plate, B, is securedwhich is provided at one corner with a hole, B', for pivoting said wingon the top of the upright 'frame A, as shown at B3, Fig. 4, the framebeing provided with a central projection or bar in which one end of thepivot rests, the other end of the pivot being in the side piece of theframe. The plate B is also provided with the eye O,to which a lever,D,ispivot-ed, the other end of which is pivoted to the middle of a bar, A3,which is of a shape similar to that of the letter V, but may have anyother suitable shape, the ends of said bar A3 being secured to the rod Eand the guide-rod E9, both passing through vthe vertical tubes A2,Aforming the frame A. The rod E extends down into the tube A2 asufficient distance to be properly guided, whereas the rod E extendsentirely through its tube Ai and is also guided. The two tubularstandards A2 A2, referred to above, are on one side of the frame, and inthe other two tubes A2, like rods, E and E, may be placed, and they mayalso be connected at their upper ends by a bar, A3, which may beconnected with an additional semaphore-wing in ease the apparatus is tohave two wings. ln the lower end ot' the rod E, which is in a suitablecasing, H, at or near the ground, a transverse eye or slot, E', isformed, through which a roller, F, is passed, which is pivoted on theend of a lever, G, pivoted to a bracket, G', secured on the inner sideof the easing H. On the end ofthe arm I of the bracket G a roller, J, ispivoted, which is passed through a transverse slot, K, in a lever, L,having its upper end pivoted to the lever G, and at its lower endconnected with a pulling or throwing rod, M.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. The combination, with the rod E, of the pivoted lever G, connected with the rod E, and of the lever L, providedwith atransverse slot through which a pin or roller passes, projectingfrom a fixed object, and which leverLhas its upper end pivoted to thelever G, substantially as herein shown and described.

2. The combination, with the rod E, having the eye or slot E, of thepivoted lever G, the roller F on the same passed through the slot E',the bracket G',having an arm, I, the roller .I on the said arm, thelever L, having a slot, K, through which the roller J is passed, theupper end of the said lever L being pivoted to the lever G,substantially as herein shown and described.

3. The combination, with the pivoted signal-wing A', of the rod E, thelever G, the bracket I, the lever L, having the slot K, and pivoted tothe lever G, and ofthe bar M, substantially as herein shown anddescribed.

VILLIAM THORNBURGH.
